【 摘 要 】

Retrofitting thermal power plants is a valuable opportunity to guide Taiwan’s electricity generation towards sustainability. Using an existing power plant nearing decommissioning as a case study, we hypothesized about fuel source options for retrofitting the power plant and compared the resulting impact on lifecycle atmospheric emissions. Our use of the lifecycle assessment (LCA) methodology reflected Taiwan’s heavy reliance on the imports and shipping of primary energy sources. We found that after accounting for the contribution of liquefaction and regasification (17%), gas-fired electricity still has significantly lower lifecycle greenhouse gases (GHGs) than coal or fuel oil (FO). In addition, we found that if natural gas (NG) is selected to achieve the greenhouse gas reduction of thermal power, the co-benefit of air pollution reduction can also be achieved at the same time.
